Microsoft SQL Server: TSQL Formatting of Results Columns

All we need is an easy explanation of the problem, so here it is.

I have a result set of data that has duplicates because certain companies are tied to multiple banks is there a way to combine the values in the BankName column either into a single column.

So the result would be Bendigo Bank, *** Merchant Services on a single row

Or Split them so each row has two bank columns BankName1 with Bendigo Bank As the Value and BankName2 with *** Merchant Services As the value
